[Evolution] Font rendering

[Ralf Mardorf <silver bullet zoho com>]

Hi,

I always noticed that font rendering for Evolution email text differs
from the font rendering of other applications, what ever theme I chose.

Now I decided to use a theme with not completely black fonts, instead of
000000 the font colour is nearly black 202020.

My first thought was that there is an issue with the theme, that I did
not change all font colours from this theme with a default of 5A5A5A to
the wanted 202020, but seemingly I was mistaken. The fonts became
darker, but due to the broken font rendering they appear brighter and as
always for Evolution only, with unwanted colours caused by the
rendering.

This effect also happens when Adwaita is used. I already noticed it when
I used a CRT, but I migrated to a LCD and now it's much more worse.

How could I fix font rendering for Evolution?

Evolution preferences first were set to use the same fonts as other
applications, but since "other apps" sometimes actually use their own
fonts, I selected to chose "Monospace Regular 12" for "Fixed Width
Fonts", as used by other apps, but the rendering still differs.

$ cat .gtkrc-2.0 | grep -v "#"

$ cat .config/gtk-3.0/settings.ini
